Abstract:
Objective To explore the changes of cognition and sleep status in the youngsters with internet addiction disorder (IAD), and to clarify the relation between cognition and sleep-related indicators of IAD youngsters.Methods Event related potential (ERP) and Pittsburgh Sleep Quality Index (PSQI)test were used for forty-two IAD (case group)and forty non-IAD (control group) in youngsters, and the indexes of period latency (PL)of N1 ,P2 ,N2 ,P3 and amplitude of P3 (P3 amp)of ERP were analyzed,the factor scores of sleep quality (SQ), sleep latency (SL), sleep time (ST), sleep efficiency (SE), sleep dysfunction (SD), sleeping pills (SP), daytime dysfunction (DD)and total score of PSQI were analyzed. The correlation between the P3 PL, P3 amp of ERP and all the indexes of PSQI in case group was analyzed.Results The PL of N2 ,P3 of ERP in case group was significanly longer and the P3 amp was significantly lower than those in control group (P<0.01);the factor scores of the SQ,SL,ST,SE,SD,DD,and the total score of PSQI test had significant differences between two groups (P<0.01).The correlation analysis results showed that there were remarkable positive correlations between the P3 PL and the factor seores of the SQ,SL,ST,SE,SD,DD and the total score of PSQI test in case group (r=0.46,0.34,0.51,0.40,0.48,and 0.54;P<0.01),and there were remarkable negative correlations betweeb P3 amp and the indexes of PSQI test in case group (r=-0.42,-0.45,-0.49,-0.38,-0.38,and -0.50;P<0.01).Conclusion The IAD youngsters have cognition and sleep dysfunction,and the both factors can affect each other.
